Here's a shortlist of possible uses for the Command pattern:
- Undo: Implementing an undo/redo system that you find in most text and image editors.
- Macro: A macro recording system with which players can record a sequence of attack or defensive combos. Then, assign them on an input key to execute them automatically.
- Automation: Automate processes or behaviors by recording a set of commands that a bot will automatically and sequentially execute.
In conclusion, it's a good pattern for features related to storing, timing, and sequencing user inputs. And if you get very creative with it, you could create some compelling game systems and mechanics.
